11 Claims.

This invention relates to the installation of door sections in sectionalbuilding walls, and more particularly in walls of the metallic knockdowntype. It is customary in the erection of metal partitions to install allpanel sections and door sections at a common level determined by thehighest point in the floor and this has occasioned unnecessarily largeclearances under doors which occur at locations where the floor level islow. It frequently occurs that doors are installed with a minimum ofclearance underneath and rugs or other floor covering are laterinstalled making it necessary to increase the clearance under the doorin order that it may 5 swing over the rug. It is highly desirable thatit be possible to readily adjust the clearance under the doors in orderthat it may always be the minimum suitable to the location and use ofthe door. It is among the objects of this invention to provide a doorwhich is readily adjustable in elevation to meet the requirements ofuneven floors and varying thicknesses of floor covering. Other objectsand advantages will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention,then, consists of the features hereinafter fully described andparticularly pointed out in the claims, the following description andthe annexed drawing setting forth in detail but a few of the variousways in which the principle of the invention may be applied.

In said annexed drawing:--

Fig. I is a front elevation-a1 view of a portion of a wall made inaccordance with this invention and illustrates a door section andportions of two panel sections; Fig. II is a partial section on largerscale taken along the line II-II of Fig. I with the door leaf removed;Fig. III is a sectional view along the line III-III of Fig. I; Fig. IVIs an isometric view of a portion of a clamp plate; Fig. V is anisometric view of the upper comer portion of a strike frame; Fig. VI isan isometric view of a lower corner of a strike frame; and Fig. VII is ahorizontal section of a form of strike frame which requires no clampplate.

In the form illustrated, a wall is constructed of a series of panelsections and door sections assembled in horizontal relationship to eachother, the end verticals of each section constituting half posts whichmay be secured together in any suitable manner. The invention is equallyapplicable to walls in which separate posts or supports are interposedbetween adjacent panel or door sections. The support members orverticals of each section are shimmed or otherwise elevated to a commonlevel as indicated by line LL of Fig. I, by means of shims S or othersuitable means. A strike frame is provided made up of the horizontalmember 20 and the vertical members 30 which may be installed in threepieces or welded into a solid frame. Suitable hinges or butts H areprovided, and a door leaf D is mounted in the strike frame.

The strike frame and door are securely mounted against the supportmembers, but in such a manner as to permit vertical adjustment. For thispurpose we prefer to form the support member V with a longitudinalgroove 31. A clamp plate 40 is provided to nest within the verticalmember 30 of the strike frame. This clamp plate is further provided witha rib 41 to fit loosely within groove 31 of the vertical and obstructthe passage of light between the strike and the vertical.

Suitable embossings 42 are provided at intervals in the clamp plate toaccurately position it on the vertical with respect to the groove. Theseembossings may be tapped to receive a screwth readed member 32 whichserves to clamp the strike frame securely against the vertical. Suchscrew-threaded members pass through slotted holes 24 in the verticalthereby permitting relative movement. The clamp plate may be welded tothe strike frame or may be slidable axially therewithin.

Another form of construction is illustrated in Fig. VII. The strikemember is provided with integral outstanding flanges which enter agroove 31 of a vertical member V. The bolts are placed with their headswithin the strike member by sliding into position from one end, meansbeing provided to prevent rotation when in place. The vertical is thenbrought into assembled relation and nuts are provided to completethe'assemblage.

A panel member 21 is also carried by the support members. In thepreferred form cleats or semi-punchings 23 are provided on the supportmembers and the panel member is located thereby and held in place bymeans of a through-bolt 25 passing between the supports at either end ofsuch panel member. The panel member may, of course, be welded orotherwise secured to the support members. A floating or telescopicmember 22 is provided to overlap the panel member and the strike frameand provide a finished appearance as the strike frame is movedrelatively to the panel member. This floating member may take the formof upstanding legs on the strike frame entering an opening in the panelmember or vice versa, but we prefer to provide a separate part slideablewithin both the strike frame and the panel member in order to permit themaximum relative motion. In the preferred form this floating member maybe a. channel with the flanges rebent outwardly as at 26 to preventwithdrawal from the member which it engages. The web of such channel maybe provided with spacer platesji'l welded or otherwise fixed thereon.Such spacer plates or outwardly directed flanges may serve the furtherpurpose of centralizing the floating member and preventing scratching ofthe finish.

Itwill thus be seen that this construction as a whole is adaptable towidely-varying condi- 1 tions, as the door clearance is adjustable tomeet hinges has greater clearance than the other.

In the construction illustrated the support members constituting the endverticals of adjacent panel sections and door sections are secured inspaced relationship by means of clip C and facing members P areremovably secured to such clips to provide a finished appearance andready access to the clamping screws 32 which are wholiy concealed in thecompleted structure.

Other modes of applying the principle of the invention may be employed,change being made as regard the details disclosed, provided the meansstated by any of the following claims, or the equivalent of such beemployed.

We therefore particularly point out and distinctly claim as ourinvention.
